Yield:880549-30-4 98%

Reaction Conditions:

with hydrogenchloride in methanol;water at 70; for 1 h;

Steps:

1

In a 50 mL round-bottom flask, the compound of the Formula I (0.258 g, 0.738 mmol) was dissolved in reagent grade methanol (5 mL) to generate a colorless solution. The solution was diluted with water (15 mL) and then aqueous hydrochloric acid (0.0978 N, 7.56 mL, 1 equiv.) was added in one portion. The resulting mixture was stirred at 70° C. for one hour. The solvents were removed in vacuo and the resulting clear glass residue was dissolved in water (5 mL) and transferred to a 30 mL plastic bottle. The solution was frozen with liquid nitrogen and then lyophilized over two days to yield a fluffy white solid which was subsequently ground to a fine white powder of the hydrochloride salt of the compound of the Formula I (0.280 g, 98%). HPLC: 98% (>99% ee). GC: CH2Cl2 (5 ppm), EtOAc (4 ppm), MeOH (0 ppm). Anal. Calcd. for C21H27N5.1.1 HCl.1.4H2O: C, 60.81; H, 7.51; N, 16.88; Cl, 9.40. Found: C, 60.80; H, 7.20; N, 16.81; Cl, 9.40.
